A San Bruno man is facing charges for drinking while driving a San Francisco Deluxe Sightseeing tour bus.

A San Francisco tour bus driver who's facing DUI charges was reportedly pulled over earlier this month after police saw him "struggling to steer the bus while holding the microphone."

Leon Maynard, 60, of San Bruno pleaded not guilty Monday to the charges stemming from the July 5 incident, prosecutors said.

Maynard was reportedly driving a San Francisco Deluxe Sightseeing tour bus that was stopped by police near Stockton and Post streets about 1:15 p.m. that day.

When police officers approached the coach, they allegedly spotted three bottles of E&J Brandy on the windowsill of the bus, including two that were travel-size and a third bottle that was slightly bigger.

On Monday, Superior Court Judge Samuel Feng ordered Maynard, who is out of custody, to return to court Aug. 19 for a pretrial hearing. Maynard also was ordered to not operate a motor vehicle while the case is pending.
